Specific interaction modes in the crystal structures of oligofluorinated tolanes featuring additional electron donor and acceptor groups

A series of partially fluorinated and specifically para-substituted tolanes (1-4) have been synthesized via palladium-catalyzed Sonogashira cross-coupling reaction. The single-crystal structures have been determined by X-ray diffraction. The molecules ado

SYNTHESIS OF SUBSTITUTED POLYFLUORO-AROMATIC ACETYLENES

Reaction of pentafluoro-aromatic acetylene compounds with large excesses of nucleophilic agents using K2CO3 as base gave polysubstituted and monosubstituted polyfluoro-aromatic acetylenes.

A Convenient Synthesis of Fluoro-Aromatic Acetylene Derivatives

The coupling reaction between polyfluoroiodobenzenes and terminal acetylenes under the catalysis of bis(triphenylphosphine)palladium dichloride and copper(I) iodide in triethylamine afforded a simple and effective method for the synthesis of fluoro-aromat
